Title: Developing device for image forming device
Inventor: TANAKA YOSHIAKI
IPC: G03G21/20
Filed: 1988-06-13
Abstract: PURPOSE:To prevent toner from partially and excessively sticking to a developing roller and to prevent a partial change in pressure between the developing roller and a photosensitive drum by reversing the partial deformation of the developing roller within an allowance range and after that, starting developing action. CONSTITUTION:When a copying machine is not operated, the developing roller 22 is stopped, and its contact position with the photosensitive drum 4 and its abutting position on a regulation blade 24 are not changed. Thus, pressure is concentrated on the same place and the periphery of the developing roller 22 is deformed. Therefore, after a power source is turned on and an atmospheric temperature becomes one that is set beforehand, the rotation of the developing roller 22 is started. The developing roller 22 is rotated after it is made into a state where it is easy to be reversed so that a time until it is reversed is reduced. Moreover, the developing roller 22 is made into a state where printing can be started after it is rotated for a specified time after rotation is started. Thus, printing and developing are started after the deformation of the developing roller 22 is eliminated. Therefore, the toner does not partially and excessively stick to the developing roller and normal image formation is performed.

Title: Variable gain amplifier for loudspeaker
Inventor: IGARASHI YOSHITO
IPC: H03G3/32
Filed: 1978-11-20
Abstract: PURPOSE:To secure stabilization for the speaker output without the extreme change through the average gain control by increasing the gain to the noise input and at the same time giving no increment of the gain to the discontinuous sound waves respectively. CONSTITUTION:The input signal applied to input terminal 1 is amplified through amplifying transistor Tr8 and power amplifier 3 and then sent to speaker 4. In case the noise is detected by mike 5, the noise is amplified via amplifier 6 and then rectified 7 to be charged to capacitor 11. While Tr10 changes the impedance according to the charging electric charge of capacitor 11 and varies the amplification level of Tr8 to increase the gain to the noise wave. In this case, the output of rectifier 7 is applied to Tr12 and 13 through diodes 14 and 19 to avoid the gain increment to the intermittent or discontinuous sound waves of the announcement or the like. As a result, the speaker output can be stabilized with no extreme change through the average gain control.

IPC: H01L21/027
Filed: 1982-08-19
Abstract: PURPOSE:To prevent the production of any reverse whisker, by reducing the quantity of light reflected by a stepped surface of an insulating film on which a metal coating is mounted. CONSTITUTION:On the surface of a field oxide film 21, a metal coating 24 is formed, followed by a silicon nitride coating 25 high in light absorbance and a positive-type resist film 26 with high light absorbance containing a coloring matter. Then, exposure is effected with a mask 27 having a predetermined pattern used as a shielding plate. The quantity of light for the exposure is set so that the light reflected by an inclined surface 22a of the field oxide film 21 is weakened so as not to produce any reverse whisker, that is, about 79% of a standard exposure amount. The inclination angle (theta) of the inner peripheral surface 22a of a gate hole 22 as a stepped surface of the field oxide film 21 is set to be 40- 50 deg.. Thus, the stepped surface has a reduced light-receiving area when the positive-type resist film 26 is treated by exposure, and the light is practically prevented from being reflected to reach the resist film portion corresponding to the pattern for the gate electrode wiring or the like.

Title: Discharging preventing system for memory back-up power source part
Inventor: SUGIYAMA KAZEO
IPC: G06F1/32
Filed: 1987-06-10
Abstract: PURPOSE:To prevent the discharging of a power source part for back-up when the back-up is not required by releasing selectively a switch device at the time of turning the power source off, and separating the power source part for back-up from a memory part. CONSTITUTION:When a switch SW is closed and a power source S is turned on, an output voltage VCC is impressed through a diode D2 to a buffer memory BM, simultaneously, a relay Ry is operated and a contact (r) is closed. Thus, a charging current flows through a resistance R to a power source Ba for back-up, and therefore, the power source part Ba is charged. Here, when the power source S is turned off by the power failure, etc., the output voltage VCC is eliminated, a relay Ry is returned, and the contact (r) is opened. Since the switch SW is closed, the power source part Ba backs up the memory BM through a diode D1. Consequently, the data before the power failure stored into a buffer memory are held as they are.
